shown :in Figs. l and 2. l'labr 3B is pertorated at its ends, circular ball bearings ll being provided in the perforao enable the har lli-l tdffrcely slide posts l and i." Between the posts l5 and 16, la. centrally perforated plate Qdis se ned to the upper frame of the aeroplanel and bracket 21 may be secured thereto, inf/made integral therewith. ln this bracket 21, sha ed as shown in Fig. to 'ornra 44 'underneath the aperture e8 in tl ate '2O and the flange 49, the locking ami asing mechanism of the paniclnite is nnainted. The locking and releasing mechanism comprises,"-besides the Ell, also the bolt 22, a collar 2o and formed thereon., bearings in the bracket filler the bolt 22, and sonic suitable mechanism for reciprocating the bolt in bearings, for instance the .spring 42li, and the pull-rope 52S, connected to the bolt 2Q, The holt jouroaled in the bracket 2l, as shown in ll" and between the flange i9 of. the bracket and the collar thc spring 25 is bracket o4 slid thereon. The purpose of this spring is hel to keep the bolt .ing with the ring 3i), when the latter is. drawn. Pull-rope is attached to the eye l of the bolt and passed over the pulley 7 nrouru'zed in lugs 52S, secured to the bar position to bring the drop end of the oper Where it may loe conveniently hed from the aviators seat.. In place of pnllrope, a suitable lever arrangement nniy be employed for moving the bolt. I have, however, determined upon the means sho i and described, knowing from rieucc, that by "thisarrangement the gre t probability of confusion, and of. the

resulting therefrom, are avoided. im. parachute normally folded upon the aeroplane..` It is held in its inactive osition and place by the bolt 22, interlocking wit the ring 39, as above explained. The

`on oi" the covering 32 of the parachute. or rhauging the traine and thel ropes, connecting' it with the aeroplane, are gathered and folded under the frame forward and att; those 'at the sides are drawn out and folded with the covering as shown in Fig. 3. To :facilitate a quick spreading out of the parach cover, tiny folded covering 32 and the ropes 1re laid out toward the wings of the aeroplane, and then, alter being folded cngth'wise, are laid in transverse folds, oi'

2Q in its position, interlock-f withdrawing of the covering 32 from underneath of the straps by the pulling (lifting) action, exerted upon its central portion by the force of the springs 31, when reacting upon -thebar 33 of the frame of the para chute.

The releasing aud sprczuling of the parathe frame 'andthe parachute cover, secured thereto, upwardlyalong the posts l5 and 16.

This action ofthe springs, 31 lifts the parachute 'for' a sullicient distance''o admit a rapidinflow of air underneath, to inflate the parachute. lt lwill be noted, as shownin iig. 2,`and as hcrcinbeforc explained, that the 4area of the parachute largely exceeds that ofthe 'f ieroplane, and. that the connecting ropes are secured to the aeroplane so as to support it over its center of gravity. The center of gravity will then, of course, be so inuch'below Where it originally was, in thc'aeroplane, as the supportingl resist. ance is transferred from the planes 18 to the parachute, and when the' ropes 40 are stretched out, the parachute breaks and be gins to retard the decent of the 'aeroplane The frame of the parachute being permanently spread,'and so constructed, that the force, initially raisin the parachute, acts directly upon it to li the parachute from the aeroplane; the dan r of any mistake ox' failure in launching t e parachute is obviated. The nido-posts 1'5 and16, co erating with t e rig1d frame, prevent a s1dewisc displacing of the parachute, andas the springs 3l raise the parachute a sucient distance from the aeroplane to insure the inflow of air underneath the parachute in sufficient volume to fill it, any tendency of the aeroplanev to turn over, as it mayr have, in case of displacement 0f its center of gravity in case of accident, or of an error of the aviator in operating the steering devices, is thereby overcome, or at least sulliciently countcracted to prevent it.

l The objects of my invention are thus attained by the herein described construction of' the parachute, the manner of its connecti e combination with the aeroplane, and by the cooperative action therewith of the mechanism for safely, and practically instantancous'ly,` setting the parachute in action.

I claim as my invention: 1. A parachute attachment for aeroplanes, comprising a rigid frame, approximately tso plane, a covering of greater area than the' ironie,v secured rliereto; ropes7 connecting .the ,edge of the Vcovering with the frame- -aerop1ane,' and means for guiding end. hold;
